Description

Technical Field

[0001] This utility model belongs to the field of high voltage connector technology, specifically referring to a main connector device. Background Technology

[0002] The high-voltage grounding clamps commonly used during the maintenance of existing 10kV railway power distribution substations mostly adopt a duckbill-type structure, as shown in the attached figure. Figure 1 As shown, the grounding clamp connectors include a duckbill-type auxiliary connector and a flat-type main connector. The main connector is connected to the auxiliary connector via a connecting plate, and the connecting plate is connected to the grounding rod. During operation, the connector is connected to the grounding rod via copper wire. The auxiliary connector and the main connector need to work together to clamp the busbar. The busbar is a rectangular sheet structure and is high-voltage energized. During operation, the operator must wear insulated gloves, hold the grounding rod, and keep their hands as far away from the connector as possible. The connection between the connector and the grounding rod can rotate. During operation, the grounding rod is perpendicular to the connector, and the auxiliary and main connectors need to clamp the busbar laterally. Because the main connector is a flat structure and the copper wire is relatively heavy, and the connection between the connector and the grounding rod can rotate, unstable clamping and easy disconnection of the connector often occur during operation, resulting in insufficient connection stability of the existing connectors. In addition, due to the tight maintenance time, maintenance personnel may hold the grounding rod forward with their hands to reduce the impact of gravity when they cannot connect it multiple times, which poses a certain safety risk. Utility Model Content

[0003] The purpose of this utility model is to provide a main terminal clamp device that, when used in conjunction with the existing auxiliary terminal clamp, can stably clamp the busbar and prevent it from falling off, thereby increasing the stability of the connection and reducing safety risks.

[0004] To achieve the above objectives, the present invention provides a main connector clamp device, comprising a main connector clamp and auxiliary hooks. The main connector clamp includes a connector connection part and a clamping part. The starting end of the connector connection part is connected to the connecting plate of the connector clamp, and the tail end of the connector connection part is connected to the starting end of the clamping part, and the two parts are integrally formed. The front side of the clamping part is a flat surface with a grid-like groove, which extends to the edge of the front side of the clamping part. Two bottom grooves are arranged parallel to each other on the back side of the clamping part, and auxiliary hooks are provided in the bottom grooves.

[0006] As a further embodiment of this utility model: the size of the auxiliary hook is adapted to the bottom slide groove, the starting end of the auxiliary hook contacts the starting end of the bottom slide groove, the tail end of the auxiliary hook is a hook facing the front of the clamping part; a first limiting block and a second limiting block are provided on the outside of the long side wall of the auxiliary hook, the first limiting block is close to the starting end of the auxiliary hook, the second limiting block is located in the middle part of the long side wall of the auxiliary hook, the first limiting block and the second limiting block are on the same horizontal line, the interior of the auxiliary hook is a rectangular hollow structure, a spring baffle is connected to the interior near the starting end, the upper plane of the spring baffle is flush with the upper plane of the auxiliary hook, the length of the spring baffle is less than the length of the auxiliary hook, the thickness of the spring baffle is less than the thickness of the starting end of the auxiliary hook, the starting end of the compression spring is fixedly connected to the plane below the spring baffle and connected to the auxiliary hook, the end of the compression spring is close to the tail end of the auxiliary hook, after the auxiliary hook is installed into the bottom slide groove, the end of the compression spring contacts the baffle of the bottom slide groove.

[0007] As a further embodiment of this utility model, the clamping part is a cuboid structure.

[0008] As a further embodiment of this utility model: the width of the baffle is smaller than the width of the bottom groove, and it is located at the center of the tail end of the bottom groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an auxiliary hook and spring on the main terminal clamp, the main busbar is secured and will not come loose. The flat surface of the grid-like groove on the front of the main terminal clamp further increases the friction during the clamping process. The reinforcing ribs on the back of the main terminal clamp further improve the strength of the main terminal clamp device. When the auxiliary hook needs to extend forward, the baffle blocks the spring, and the second limiting block can fall into the limiting recess, further fixing the auxiliary hook and limiting the excessive extension of the auxiliary hook. This main terminal clamp device, when used in conjunction with the existing auxiliary terminal clamp, can stably clamp the busbar and prevent it from falling off, increasing the stability of the connection and reducing safety risks.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 2 to 5 As shown, a main connector clamp device includes a main connector clamp 1 and an auxiliary hook 2. The main connector clamp includes a connector connection part 11 and a clamping part 12. The starting end of the connector connection part 11 is used to connect to the connecting plate of the connector clamp, and the tail end of the connector connection part 11 is connected to the starting end of the clamping part 12, and they are integrally formed. The clamping part 12 has a cuboid structure, and the front surface of the clamping part 12 is a plane with a grid-like groove extending to the edge of the front surface of the clamping part 12. This arrangement can increase the friction on the clamping surface. The front surface of the clamping part 12 is close to the auxiliary connector clamp and contacts one side of the busbar during use. Two bottom grooves 14 are arranged parallel to each other on the back. To increase the strength of the main connector 1, a reinforcing rib 13 is provided between the bottom grooves. A baffle 16 is provided at the end of the bottom groove 14 away from the connector connection part 11. The baffle 16 is located at the tail end of the clamping part 12. The width of the baffle 16 is smaller than the width of the bottom groove 14 and is located at the center of the tail end of the bottom groove 14. An inner groove 17 is horizontally provided on the inner long side wall of the bottom groove 14. The inner groove 17 penetrates the inner long side wall. A limiting notch 15 is provided above the inner groove 17 near the baffle 16. The limiting notch 15 extends upward to the upper plane of the bottom groove 14.

[0018] The bottom groove 14 is used to hold the auxiliary hook 2. The size of the auxiliary hook 2 is adapted to the bottom groove 14. The starting end of the auxiliary hook 2 contacts the starting end of the bottom groove 14. The tail end of the auxiliary hook 2 is a hook 23, which faces the front of the clamping part 12. A first limiting block 21 and a second limiting block 22 are provided on the outside of the long side wall of the auxiliary hook 2. The first limiting block 21 is close to the starting end of the auxiliary hook 2, and the second limiting block 22 is located in the middle of the long side wall of the auxiliary hook 2. The first limiting block 21 and the second limiting block 22 are on the same horizontal line and are embedded in each other. Installed in the inner groove 17 of the bottom slide groove, the auxiliary hook 2 has a rectangular hollow structure inside. A spring baffle 24 is connected to the inside near the starting end. The upper surface of the spring baffle 24 is flush with the upper surface of the auxiliary hook 2. The length of the spring baffle 24 is less than the length of the auxiliary hook 2, and the thickness of the spring baffle 24 is less than the thickness of the starting end of the auxiliary hook 2. The starting end of a compression spring is fixedly connected to the plane below the spring baffle 24 that connects to the auxiliary hook 2. The end of the compression spring is close to the tail end of the auxiliary hook 2. After the auxiliary hook 2 is installed into the bottom slide groove 14, the end of the compression spring contacts the baffle 16 of the bottom slide groove 14. The baffle 16 is used to resist the spring. During the forward movement of the auxiliary hook 2, the spring force controls the hook 23 to not move too far and generates a clamping force, making the hook 23 hook the busbar more firmly. The overall wiring clamp will not fall off when clamping the busbar, avoiding safety risks.

[0019] The working process of this utility model is as follows: During use, the auxiliary hook 2 can move forward along the inner groove 17 to easily hook the busbar. The bent hook 23 hooks onto the edge of the busbar, and the holding force is further enhanced under the action of the spring. The second limiting block 22 can be fixed to the limiting recess 15, thus stabilizing the auxiliary hook. Combined with the auxiliary wiring clamp, it can firmly clamp the busbar, preventing it from falling off. Furthermore, this main wiring clamp device increases the contact area with the busbar, and the reinforcing ribs increase the overall strength. The spring compresses and stores energy when the auxiliary hook extends forward, releasing the force when the bent hook 23 is removed, achieving the purpose of resetting the device. When the hook 23 moves to a certain length, the second limiting block 22 falls into the limiting recess 15, preventing the hook from extending too far. This device, used in conjunction with the existing auxiliary wiring clamp, can stably clamp the busbar, preventing it from falling off, increasing the stability of the connection, and reducing safety risks.
